Re: [Geopriv] [GEOPRIV] Liberty Alliance

Hi Alberto,

thanks for the details. The initial version, which was published some 
time ago, had support for SAML, see for example 
http://tools.ietf.org/html/draft-winterbottom-http-location-delivery-03.
However, this support was removed later on (since it is not necessarily 
totally for free).
Addittionally, the ability for the HELD client to publish authorization 
policies in the style of Geolocation Policies (as developed by the 
working group) have also been removed since there are also issue with 
regard to complexity in this specific deployment case.

The basic idea was to create something simple to start with and then 
worry about more sophisticated functionality later. I don't think anyone 
of us in the group is currently working on SAML/Liberty Alliance for HELD.

I hope my answer helped.

Ciao
Hannes
